Emirates Nuclear Energy (ENEC) has concluded cold hydrostatic testing (CHT) work at unit two of the Barakah nuclear energy plant in the United Arab Emirates (UAE).

This evaluation follows a number of CHT tests conducted at unit one last year and represents ENEC’s commitment to achieving high safety standards.

The CHT has verified that the welds, joints, pipes, and components of the reactor coolant system and associated high-pressure systems comply with Federal Authority for Nuclear Regulation (FANR) regulations. The tests have also helped to prepare unit two for nuclear operation.

ENEC CEO Mohamed Hammadi said: “The completion of CHT means that the second unit is closer to achieving its goal of enhancing energy security for the UAE, as well as its environmental sustainability, by supplying the UAE with electricity produced with near-zero carbon emissions.”

Prior to the tests, the unit’s nuclear steam supply systems (NSSS) were flushed with demineralised water.

Once the reactor pressure vessel head was installed, the CHT used reactor coolant pumps to circulate previously processed water through the primary circuit. These pumps are designed to help maintain the required operating temperature inside the reactor during operation.

Korea Electric Power (KEPCO), Korea Hydro and Nuclear Power (KHNP), FANR, and Nawah Energy Company were also involved in the CHT test.

When completed, the Barakah plant is expected to supply up to 25% of the electricity demands in the UAE.
